Londoners face transport chaos at the start of the working week after two unions representing workers on the London Underground said they would go ahead with a 24-hour strike from Sunday evening.
Metro operator Transport for London (TfL) said most stations in central London would be closed due to the action by the RMT and TSSA unions in a dispute over staffing levels after the closure of ticket offices in recent years.
The walkout on the Tube is part of a wave of strikes hitting British rail and air passengers at the start of 2017.
